The next generation of Mercedes-Benz’s wonderful SL-class roadster has been running around for over a year now. First caught wearing camouflage that resembled vinyl siding, the car is beginning to lose its plastic disguise as it progresses toward launch. Now we’ve even caught a glimpse of the interior.

These new pictures reveal an SL that carries an overall shape very similar to the outgoing car, but its disguise still hides some fine (and likely new) details such as the character lines on the car’s flanks. You’ll notice the more-upright nose, smoothed tail, and—most notably—the SLS-like interior, but the rest of the design is intentionally restrained, according to the car’s chief designer, Gorden Wagener.

Engine displacement is expected to shrink, but horsepower will not. We know the next SL will adopt the new twin-turbo, 4.7-liter direct-injection V-8 found in the 2011 CL550, and should be tuned for around 429 hp.
